Reciprocal association between pain and quality of life after newly acquired spinal cord injury.

PURPOSE: Pain is highly prevalent in spinal cord injury (SCI) and a key determinant of quality of life (QoL). This is the first study to examine reciprocal associations between pain and QoL in patients undergoing their first inpatient rehabilitation after SCI. METHODS: Longitudinal data, with three measurement time points (1 month and 3 months after SCI onset, and at discharge from inpatient rehabilitation) from the Inception Cohort of the Swiss Spinal Cord Injury Cohort Study. Participants were 381 individuals aged ≥ 16 years with a newly diagnosed traumatic or non-traumatic SCI. 75.1% were male and the average age was 53.2 years. Random intercept cross-lagged panel models were conducted to examine the reciprocal association between pain intensity and QoL, as measured with the International SCI QoL Basic Data Set three individual items (satisfaction with life, physical health, and psychological health) and total score (mean of the three individual items). RESULTS: Both item and total QoL scores increased over time. 1 month: 5.3 (SD = 2.7), 3 months: 5.9 (SD = 2.3), discharge: 6.6 (SD = 2.0). Participants reported relatively low levels of pain intensity that remained stable over the course of inpatient rehabilitation. 1 month: 2.7 (SD = 2.3), 3 months: 2.6 (SD = 2.4), discharge: 2.7 (SD = 2.5). There were no significant cross-lagged associations between QoL and pain intensity across time. CONCLUSION: Results indicate that pain intensity does not predict changes in QoL during first rehabilitation, and vice versa. Associations between pain intensity and QoL reported by previous studies may be attributable to individual characteristics and timely events that simultaneously influence pain and QoL.

Risk factors of major complications after flap surgery in the treatment of stage III and IV pressure injury in people with spinal cord injury/disorder: a retrospective cohort study.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To identify risk factors associated with major complications after flap surgery in people with spinal cord injury or disorder (SCI/D) and stage III and IV pressure injury (PI). SETTING: Swiss hospital specialized in the treatment of people with SCI/D using the Basel Decubitus Approach. METHODS: We examined 60 risk factors for major postoperative complications in PIs over sacrum/coccyx, ischium or trochanter between 01/2016 and 12/2021. We performed descriptive analysis and computed global p-values using likelihood ratio tests adjusted for clustering of PIs in individuals. RESULTS: We included 220 PI treatment procedure from 149 individuals. The study population consisted of 163 (74%) men, 133 (60%) traumatic SCI, 136 (58%) stage IV PI, 198 (90%) individuals with paraplegia, 93 (42%) with osteomyelitis, and 85 (39%) with recurrent PI. Major complications 42 (19%) occurred more often in individuals with stage IV PI (p < 0.01), individuals without osteomyelitis (p < 0.03), and individuals with pathological blood concentrations of cystatin c (p < 0.028), calcium (p < 0.048), and vitamin B12 (p < 0.0049) as well as normal blood concentrations of HbA1c (p < 0.033). Immobilization (p < 0.0089) and hospital stay (p < 0.0001) of individuals with major complications was longer. CONCLUSION: In the Basel Decubitus Approach, stage IV PI, absence of osteomyelitis, reduced vitamin B12 and calcium, elevated cystatin c, and normal HbA1c should be addressed to reduce major complications.

Mean kurtosis-Curve (MK-Curve) correction improves the test-retest reproducibility of diffusion kurtosis imaging at 3 T.

Diffusion kurtosis imaging (DKI) is applied to gain insights into the microstructural organization of brain tissues. However, the reproducibility of DKI outside brain white matter, particularly in combination with advanced estimation to remedy its noise sensitivity, remains poorly characterized. Therefore, in this study, we investigated the variability and reliability of DKI metrics while correcting implausible values with a fit method called mean kurtosis (MK)-Curve. A total of 10 volunteers (four women; age: 41.4 ± 9.6 years) were included and underwent two MRI examinations of the brain. The images were acquired on a clinical 3-T scanner and included a T1-weighted image and a diffusion sequence with multiple diffusion weightings suitable for DKI. Region of interest analysis of common kurtosis and tensor metrics derived with the MK-Curve DKI fit was performed, including intraclass correlation (ICC) and Bland-Altman (BA) plot statistics. A p value of less than 0.05 was considered statistically significant. The analyses showed good to excellent agreement of both kurtosis tensor- and diffusion tensor-derived MK-Curve-corrected metrics (ICC values: 0.77-0.98 and 0.87-0.98, respectively), with the exception of two DKI-derived metrics (axial kurtosis in the cortex: ICC = 0.68, and radial kurtosis in deep gray matter: ICC = 0.544). Non-MK-Curve-corrected kurtosis tensor-derived metrics ranged from 0.01 to 0.52 and diffusion tensor-derived metrics from 0.06 to 0.66, indicating poor to moderate reliability. No structural bias was observed in the BA plots for any of the diffusion metrics. In conclusion, MK-Curve-corrected DKI metrics of the human brain can be reliably acquired in white and gray matter at 3 T and DKI metrics have good to excellent agreement in a test-retest setting.

Effect of a computerized decision support system on the treatment approach of stage III or IV pressure injury in patients with spinal cord injury: a feasibility study.

BACKGROUND: Stage III and IV pressure injuries (PIs) in patients with spinal cord injury (SCI) require complex interdisciplinary and interprofessional treatment approaches that are difficult to implement. Practical aspects, such as information exchange and coordination, remain challenging. We investigated whether a computerized decision support system (CDSS) could increase treatment adherence and improve clinical outcomes and interprofessional collaboration. METHOD: In this feasibility study, a core team developed the initial treatment process and adapted it based on several discussions with clinical experts and information technologists. The CDSS followed the Basel Decubitus Approach and was used in a clinic specializing in SCI. Thirty patients with SCI admitted for stage III/IV PI between July 2016 and May 2017 were randomly allocated to standard or CDSS-supported care. Between-group differences in treatment adherence, complication rates, length of stay, and costs were analyzed using descriptive statistics. The use of the CDSS and potential barriers and facilitators were evaluated through interprofessional focus groups, transcribed verbatim, and thematically analyzed (30 participants). RESULTS: No differences in SCI characteristics, comorbidities, or PI characteristics (localization: ischium [number (n) = 19 PI, 63%], sacrum [n = 10 PI, 33%], recurrent PI [n = 21, 70%]) were found between the two groups. Furthermore, no statistically significant differences were observed in treatment adherence, frequency of major (20% vs. 13% between CDSS and control group) and minor (33% vs 27%) complications, and length of stay (98 [±28] vs 81 [±23] days). Healthcare professionals found the CDSS to be helpful for visualizing the treatment process. However, the high workload and difficulties in the information technology processes, such as missing reminders, slow computer performance and data processing, and poor accessibility, hindered the effective implementation of the CDSS. CONCLUSION: The implementation of the CDSS to support the treatment of stage III/IV PI in patients with SCI was feasible and included definitions of milestones, interventions, and outcomes. However, to assess the impact of the CDSS, a longer observation period is required. Further, the technical difficulties must be addressed, and solid integration of the CDSS into the clinical information system is necessary. TRIAL REGISTRATION: This quality improvement project received a declaration of no objection from the Ethics Committee of Northwest and Central Switzerland (EKNZ UBE-16/003), and ethical approval was received for the focus groups (EKNZ Req-2017-00860).

Use of professional home care in persons with spinal cord injury in Switzerland: a cross-sectional study.

BACKGROUND: Persons with spinal cord injury (SCI) living in the community often require care. The boundaries between professional home care and informal care are blurred, and it is unclear who the typical user of home care is. The objective of this study was to describe the characteristics of persons with SCI using professional home care in Switzerland, determine the frequency of home care visits, and investigate the association of sociodemographic factors, SCI-specific characteristics, secondary health conditions, and functional independence with the use of home care. METHODS: We used cross-sectional data from the 2017 community survey of the Swiss Spinal Cord Injury Cohort Study (SwiSCI). Out of 3,959 eligible individuals 1294 completed the questionnaire and were included in the analysis (response rate 33%). Using descriptive statistics, differences between home care users and non-users as well as the frequency of home care visits were investigated. The association between sociodemographic factors, SCI-specific characteristics, secondary health conditions, functional independence and the use of home care was analyzed using multivariable logistic regression. Multiple imputation was used to account for missing data. RESULTS: Of 1,294 participants, 280 (22%) used professional home care. The median weekly professional home care duration was 6 h (Q1 = 2, Q3 = 12). More home care was used in persons with lower functional independence (Odds ratio (OR) 0.30 per 10 unit decrease in the Spinal Cord Independence Measure, 95%-Confidence interval (CI) 0.24-0.37), fewer secondary health conditions (OR 0.96 per unit Spinal Cord Injury Secondary Conditions Scale, 95%-CI 0.94-0.99), tetraplegia (OR 2.77, 95%-CI 1.92-4.00), women (OR 2.42, 95%-CI 1.70-3.43), higher age (OR 1.22 per 10 years increase, 95%-CI 1.06-1.39), living alone (OR 2.48, 95%-CI 1.53-4.03), and those receiving support from an informal caregiver (OR 1.88, 95%-CI 1.27-2.77). CONCLUSIONS: This is the first study to examine the use of professional home care from the perspective of persons with SCI in Switzerland. Lower functional independence strongly predicts increased home care use. The findings showed that professional home care complements informal care and is more likely to be used by individuals with SCI who live alone, have tetraplegia, and are female.

Risk constellation of hospital acquired pressure injuries in patients with a spinal cord injury/ disorder - focus on time since spinal cord injury/ disorder and patients' age.

STUDY DESIGN: Prospective cohort study. OBJECTIVES: The aim of this study was to evaluate how time since spinal cord injury/disorder (SCI/D) and patients' age influence risk constellation for hospital acquired pressure injuries (HAPI) in patients with a SCI/D. SETTING: Acute care and rehabilitation clinic specialized in SCI/D. METHODS: We collected patients' characteristics and 85 risk factors for HAPI development in adults with SCI/D with at least one HAPI during their inpatient stay between August 2018 and December 2019. We analyzed patients' characteristics and HAPI risk factors using descriptive statistics according to time since SCI/D ( < 1 year, 1-15 years, > 15 years) and patients' age (18-35 years, 35-65 years, > 65 years). RESULTS: We identified 182 HAPI in 96 patients. Comparing patients with SCI/D < 1 year with the other groups, autonomic dysreflexia (p < 0.001), abnormal body temperature (p = 0.001), hypertensive episode (p = 0.005), and pneumonia (p < 0.001) occurred more frequently; mean hemoglobin (p < 0.001), albumin (p = 0.002) and vitamin D levels (p = 0.013) were significantly lower, and patients with time since SCI/D < 1 year scored fewer points (10-12) on the Braden Scale (p < 0.001). Comparing groups per patients' age, only the SCIPUS score was higher in patients > 65 years compared to the other two groups (p = 0.002). CONCLUSIONS: Different risk factor constellation seem to be underlying HAPI development with more differences in patients time since SCI/D than patients' age. Awareness of these differences in risk factor constellation depending on time since SCI/D in these patients might lead to different HAPI prevention strategies. SPONSORSHIP: The study team didn't receive any additional sponsorship.

Prevalence of an insufficient vitamin D status at the onset of a spinal cord injury - a cross-sectional study.

STUDY DESIGN: A cross-sectional study. OBJECTIVE: This study aimed to investigate the vitamin D status after acute spinal cord injury (SCI) onset. SETTING: Specialized SCI rehabilitation center in Switzerland. METHODS: Patients admitted to the center after an acute SCI onset were included. The prevalence of a deficient (25(OH)D ≤ 50 nmol/l), insufficient (50 < 25(OH)D ≤ 75 nmol/l) and sufficient (25(OH)D > 75 nmol/l) vitamin D status were determined after admission. Vitamin D status was compared between different patient groups based on demographic and SCI characteristics. The occurrence of bed rest, falls and pressure injuries were also assessed. RESULTS: In total, 87 patients (median (interquartile range); 53 (39-67) years, 25 females, 66 traumatic SCI, 54 paraplegia) were included. Assessed a median of 15 (9-22) days after SCI onset, median vitamin D status was 41 (26-57) (range 8-155) nmol/l. The majority of patients had a deficient (67%, 95% confidence interval (95% CI) 0.56-0.76) or insufficient (25%, 95% CI 0.17-0.36) vitamin D status. A moderate negative correlation was found between vitamin D status and body mass index (p = 0.003). A moderate positive correlation was found between vitamin D and calcium status (p = 0.01). CONCLUSION: A deficient or insufficient vitamin D status directly after SCI onset is highly prevalent. Vitamin D status should be carefully observed during acute SCI rehabilitation. We recommend that all patients with recent SCI onset should receive vitamin D supplementation with a dosage depending on their actual vitamin D status.

Endocrinological and inflammatory markers in individuals with spinal cord injury: A systematic review and meta-analysis.

Spinal cord injury (SCI) can lead to dramatic physiological changes which can be a factor in developing secondary health conditions and might be reflected in biomarker changes in this elevated risk group. We focused specifically on the endocrine and inflammation profile differences between SCI and able-bodied individuals (ABI). Our aim was to determine the differences in inflammatory markers and endocrine profiles between SCI and ABI. We systematically searched 4 electronic databases for relevant studies. Human observational (cross-sectional, cohort, case-control) studies that compared biomarkers of interest between SCI and ABI population were included. Weighted mean difference between SCI and ABI was calculated using random-effects models. Heterogeneity was computed using I2 statistic and chi-squared test. Study quality was evaluated through the Newcastle-Ottawa Scale. The search strategy yielded a total of 2,603 studies from which 256 articles were selected for full-text assessment. Sixty-two studies were included in the meta-analysis. SCI individuals had higher levels of pro-inflammatory C-reactive protein and IL-6 than ABI. Creatinine and 25-hydroxyvitamin D3 levels were lower in SCI than ABI. Total testosterone levels and IGF-1 were also found to be lower, while cortisol and leptin levels were higher in SCI when compared to ABI. Accordingly, meta-regression, subgroup analysis, and leave-one-out analysis were performed, however, they were only able to partially explain the high levels of heterogeneity. Individuals with SCI show higher levels of inflammatory markers and present significant endocrinological changes when compared to ABI. Moreover, higher incidence of obesity, diabetes, osteoporosis, and hypogonadism in SCI individuals, together with decreased creatinine levels reflect some of the readily measurable aspects of the phenotype changes in the SCI group. These findings need to be considered in anticipating medically related complications and personalizing SCI medical care.

Does the socioeconomic status predict health service utilization in persons with enhanced health care needs? Results from a population-based survey in persons with spinal cord lesions from Switzerland.

BACKGROUND: Evidence suggests that the socioeconomic status (SES) affects individuals' health service utilization. Spinal cord injury is a condition that often leads to physical impairments and enhanced health care needs. It therefore presents an informative and yet under-researched case in point to investigate social inequalities in health service utilization. This study aims to describe associations between SES and health service utilization in adults with spinal cord injury from Switzerland. METHODS: We use cross-sectional data from 1,294 participants of the Swiss Spinal Cord Injury Cohort Study community survey 2017. SES was operationalized with education, household income, perceived financial hardship, subjective status, and granting of supplementary financial benefits. Health service utilization was assessed with information on visits to 13 different health care providers and four health care institutions (inpatient stays, outpatient clinics, emergency departments, specialized spinal cord centers) during the past 12 months. The dichotomized outcomes on service utilization (visited vs. not visited) were regressed on SES indicators, including adjustments for sociodemographics, lesion characteristics, and health status. RESULTS: Persons with higher SES reported higher likelihood for specialist, dentist, and dental hygienist visits and reported utilizing a larger number of different care providers. Further, specific SES indicators were associated with certain care provider visits (i.e., higher education and subjective status: higher odds for pharmacist visits; higher income: higher odds for natural healer visits; higher subjective status: higher odds for chiropractor visits; supplementary benefit granting: higher odds for general practitioner and home care service visits). We found statistically non-significant trends towards lower likelihood for inpatient stays, outpatient clinic and emergency department visits and enhanced likelihood for specialized spinal cord-center visits in higher SES groups. CONCLUSIONS: This study generally supports the claim that basic health care provision is guaranteed for all patients with spinal cord injury in Switzerland, independently of their SES. However, social inequalities were still observed for the utilization of specific providers, such as oral health care providers. Given that oral health is key for health maintenance in persons with spinal cord injury, specific interventions to enhance regular dental check-ups in lower SES groups are highly recommended.

Longitudinal measurement invariance of the international spinal cord injury quality of life basic data set (SCI-QoL-BDS) during spinal cord injury/disorder inpatient rehabilitation.

PURPOSE: This study aimed at testing the internal consistency and longitudinal measurement invariance of a brief quality of life questionnaire-the spinal cord injury quality of life basic data set (SCI-QoL-BDS)-among individuals with spinal cord injury/disorder undergoing first inpatient rehabilitation. METHODS: Longitudinal data from the Swiss spinal cord injury inception cohort study were used. Participants (n = 218) completed the SCI-QoL-BDS at one and three months post injury and at discharge. The SCI-QoL-BDS consists of three items assessing satisfaction with life as a whole, physical health, and psychological health. Internal consistency was examined at each time point and longitudinal measurement invariance was tested using longitudinal confirmatory factor analysis. RESULTS: Internal consistency coefficients ranged between .82 and .90. The confirmatory factor analysis revealed invariance of the factor structure and of all factor loadings across time. Additionally, all item intercepts except the one of satisfaction with physical health were invariant across time, suggesting partial intercept invariance of the SCI-QoL-BDS. Indeed, a response shift was observed in satisfaction with physical health. This item was evaluated more negatively in the early phase of inpatient rehabilitation, indicating the change of the evolving physical situation after the onset of a spinal cord injury. CONCLUSION: The SCI-QoL-BDS is a consistent and valid measure to assess quality of life among individuals undergoing first spinal cord injury/disorder inpatient rehabilitation. However, we recommend using latent variable frameworks instead of mean scores when examining longitudinal changes in the measure to account for potential response shift.

Predicting change in labour market participation of people with spinal cord injury (SCI): longitudinal evidence from the Swiss SCI community survey.

STUDY DESIGN: Longitudinal, population-based survey. OBJECTIVE: To examine change in labour market participation (LMP) of people with spinal cord injury (SCI) living in Switzerland and to identify predictors of increase, decrease and stability in LMP between 2012 and 2017. SETTING: Community. METHODS: Longitudinal information on LMP (i.e., weekly workload) was obtained from 311 gainfully employed, working-age individuals who participated in the Swiss Spinal Cord Injury Cohort Study (SwiSCI) community survey in 2012 and were still of working age at the time of completing the 2017 questionnaire. Statistical preselection of the predictors of change in LMP was carried out by implementing the least absolute shrinkage and selection operator (LASSO) in a multinomial logistic regression model. The final set of predictors was selected by comparison of several multinomial logistic regression models. RESULTS: Out of 311 participants, almost half (43%) changed their LMP between 2012 and 2017, 48 increased their weekly workload, 49 reduced and 37 participants left the labour market prematurely. Age at time of the survey, years of education, having children, intention to change weekly workload, high satisfaction with daily routine, extra-time needs for transportation and managing support were associated with change in LMP. CONCLUSIONS: Modifiable factors like education and satisfaction with daily routine should receive particular attention in the context of job retention strategies. More longitudinal research focusing on key employment transitions and trajectories over the life course of persons with SCI is needed to complement, validate and extend our findings.

Internal consistency and convergent validity of the International Spinal Cord Injury Quality of Life Basic Data Set at discharge from first rehabilitation.

STUDY DESIGN: This study is a cross-sectional analysis using data from the Swiss Spinal Cord Injury Cohort Study. OBJECTIVES: To examine internal consistency and convergent validity of the International Spinal Cord Injury Quality of Life Basic Data Set (QoL-BDS) at discharge from first inpatient rehabilitation. SETTING: The study was performed at four rehabilitation centers in Switzerland. METHODS: Participants were Swiss residents aged over 16 years newly diagnosed with traumatic or non-traumatic spinal cord injury (SCI). Measures included the QoL-BDS, World Health Organization Quality of Life (WHOQOL) items, Hospital Anxiety and Depression Scale (HADS), and Spinal Cord Independence Measure III (SCIM). RESULTS: A total of 495 participants were included. In all, 57% had a traumatic SCI, 71.1% a motor complete SCI, and 33.3% had tetraplegia. Mean age was 53 (SD = 16.4) years and 68% were male. No floor or ceiling effects were found. Inter-correlations were strong (0.73-0.80) and Cronbach's alpha was good (0.88). QoL-BDS mean scores were 6.4 (SD = 2.2) for life satisfaction, 5.8 (SD = 2.4) for physical health, 6.9 (SD = 2.4) for psychological health, and 6.4 (SD = 2.1) for total QoL. Correlations with reference measures were strongest for QoL-BDS total and WHOQOL general quality of life (r = 0.67), QoL-BDS physical health and WHOQOL health and daily activities (r = 0.64 and 0.53), and QoL-BDS psychological health and HADS depression and anxiety (r = -0.64 and -0.69). SCIM correlated weakly with all QoL-BDS items. CONCLUSIONS: The QoL-BDS revealed no floor or ceiling effects and demonstrated good internal consistency and convergent validity in individuals with SCI assessed at discharge from first rehabilitation. This study supports the clinical routine use of the QoL-BDS.

Predicting non-response in patient-reported outcome measures: results from the Swiss quality assurance programme in cardiac inpatient rehabilitation.

BACKGROUND: Quality assurance programmes measure and compare certain health outcomes to ensure high-quality care in the health-care sector. The outcome of health-related quality of life is typically measured by patient-reported outcome measures (PROMs). However, certain patient groups are less likely to respond to PROMs than others. This non-response bias can potentially distort results in quality assurance programmes. OBJECTIVE: Our study aims to identify relevant predictors of non-response during assessment using the PROM MacNew Heart Disease questionnaire in cardiac rehabilitation. METHODS: This is a cross-sectional study based on data from the Swiss external quality assurance programme. All patients aged 18 years or older who underwent inpatient cardiac rehabilitation in 16 Swiss rehabilitation clinics between 2016 and 2019 were included. Patients' socio-demographic and basic medical data were analysed descriptively by comparing two groups: non-responders and responders. We used a random intercept logistic regression model to estimate the associations of patient characteristics and clinic differences with non-response. RESULTS: Of 24 572 patients, there were 33.3% non-responders and 66.7% responders. The mean age was 70 years, and 31.0% were women. The regression model showed that being female was associated with non-response [odds ratio (OR) 1.22; 95% confidence interval (CI) 1.14-1.30], as well as having no supplementary health insurance (OR 1.49; 95% CI 1.39-1.59). Each additional year of age increased the chance of non-response by an OR of 1.02 (95% CI 1.02-1.02). Not being a first language speaker of German, French or Italian increased the chance of non-response by an OR of 6.94 (95% CI 6.03-7.99). Patients admitted directly from acute care had a higher chance of non-response (OR 1.23; 95% CI 1.10-1.38), as well as patients being discharged back into acute care after rehabilitation (OR 3.89; 95% CI 3.00-5.04). Each point on the cumulative illness rating scale total score increased the chance of non-response by an OR of 1.05 (95% CI 1.04-1.05). Certain diagnoses also influenced the chance of non-response. Even after adjustment for known confounders, response rates differed substantially between the 16 clinics. CONCLUSION: We have found significant non-response bias among certain patient groups, as well as across different treatment facilities. Measures to improve response rates among patients with known barriers to participation, as well as among different treatment facilities, need to be considered, particularly when PROMs are being used for comparison of providers in quality assurance programmes or outcome evaluation.

Osteomyelitis and antibiotic treatment in patients with grade IV pressure injury and spinal cord lesion-a retrospective cohort study.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To analyze characteristics and treatment of osteomyelitis (OM) in the treatment of grade IV pressure injury (PI) in patients with spinal cord injury/disorder (SCI/D) following the Basel Decubitus Concept. SETTING: Acute care and rehabilitation clinic specialized in SCI/D. METHODS: Patients with SCI/D were admitted for grade IV PI treatment between 1st January 2010 and 28th February 2015. Patients, SCI/D, and PI characteristics were collected from chart reviews. Descriptive statistics and differences between groups with and without OM were evaluated. RESULTS: In total, 117 patients (87 male, 30 female) with 130 PI grade IV were included. In 95 patients (81%), OM was diagnosed histologically. In 87 cases, more than one bacterial species was involved. Out of 49 different bacterial species, Enterococcus faecalis and Staphylococus aureus were most frequently observed. Amoxicillin/clavulanic acid and ciprofloxacin were the most frequently used out of 24 different antibiotics. Length of antibiotic treatment varied between <8 days and >91 days with 31 patients receiving antibiotics for about 8 weeks. Complications occurred in all groups of antibiotic duration. Having a paraplegia, no OM and sacral PI was associated with increased complication rates, but the number of patients did not allow comprehensive risk factor analysis. CONCLUSION: Because the variety of patients concerning SCI/D, PI, and OM characteristics did not show a conclusive relation between length of antibiotic treatment and complication rates, the development of a subgroup specific treatment concept for PI in patients with SCI/D would be favorable to further optimize antibiotic treatment.

Risk factors for hospital acquired pressure injury in patients with spinal cord injury during first rehabilitation: prospective cohort study.

STUDY DESIGN: Prospective observational cohort study. OBJECTIVES: First, describe pressure injury (PI) and associated risk factors in individuals with spinal cord injury/disorder (SCI/D) during first rehabilitation. Second, evaluate a prediction model for hospital acquired PI (HAPI) development. SETTING: Acute care and rehabilitation clinic specialized in SCI/D. METHODS: Patients ≥18 years of age with SCI/D were included during first rehabilitation between 08/2018 and 12/2019. We performed a systematic literature search to identify risk factors for PI development. Patients were classified according to HAPI developed. Between group differences of patients' characteristics and risk factors were analyzed using descriptive statistics. Logistic predictive models were performed to estimate HAPI development and receiver operator characteristic (ROC) curve was used to test the model. RESULTS: In total, 94 patients were included, 48 (51.1%) developed at least one HAPI and in total 93 were observed, mainly stage I and stage II HAPI according to the European Pressure Ulcer Advisory Panel. We found nine significantly associated risk factors: completeness of SCI/D, pneumonia, sedative medications, autonomic dysreflexia, Braden ≤12 points, SCIPUS ≥9 points, lower admission SCIM and lower admission FIM-cognition, longer length of stay (LOS) (p ≤ 0.0005). In a predictive model, none of the risk factors was associated with HAPI development (AUC = 0.5). CONCLUSION: HAPIs in patients with SCI/D during first rehabilitation are a frequent and complex condition and associated with several risk factors. No predictive model exists but with the identified risk factors of this study, larger studies can create a tailored and flexible HAPI risk prediction model.

Who are the beneficiaries and what are the reasons for non-utilization of care respite and support services? A cross-sectional study on family caregivers.

BACKGROUND: Family caregivers assume substantial caregiving responsibilities for persons with chronic conditions, such as individuals with spinal cord injury, which leads to negative impacts on their lives. Respite care and other services are provided as a temporary relief and support for them. Design of appropriate respite care programs depends on identification of beneficiary subgroups for the different types of service. This study aimed to quantify the uptake of different respite and support services for family caregivers, the reasons for non-use, and to explore the respective predictors. METHODS: A cross-sectional survey of family caregivers of persons with spinal cord injury was conducted nationwide in Switzerland. The use of 11 different respite and support services during the previous 12 months was investigated, along with caregivers' reasons for not using any respite. Classification trees were used to characterize the beneficiaries and reasons for not using respite. RESULTS: About a third of family caregivers used at least one type of respite or support service during the previous 12 months. Utilization of respite care was greater among those who employed professional home care (57% vs 24% of those without professional home care). Marked cantonal differences were also observed in utilization of respite care. The primary reason for not using respite services was "no demand" (80% of non-users of respite services), mainly among caregivers who were less emotionally affected by their caregiving tasks. CONCLUSIONS: Utilization of respite and support services depends more on place of residence and use of home care services than on functional status of the care recipient. Accordingly, programs should be tailored to the cultural context of their potential users. This is best achieved through coordination with local health care professionals who can identify needs, provide information, initiate referrals, and integrate the care into a larger support plan.

Utilization of health care providers by individuals with chronic spinal cord injury.

STUDY DESIGN: Questionnaire survey conducted in 2017 as part of the Swiss Spinal Cord Injury Cohort Study (SwiSCI). OBJECTIVES: To elucidate the use of outpatient health care providers by individuals with chronic spinal cord injury in a situation of free choice and ample supply. SETTING: Community, nationwide. METHODS: The frequency of visits was compared to that of a survey conducted five years earlier. Using regression tree analysis, the characteristics of individuals with extensive use of health care providers' services were investigated. Substitution effects, where health care users replace one provider type by another, were quantified using likelihood ratios for positive outcomes. RESULTS: The questionnaire was returned by 1,294 persons (response rate 33%). Participants reported visits to 14 different health care providers within the previous 12 months. Most often visited was the general practitioner (GP) by 82%. Older individuals used fewer health care providers than younger participants. Individuals with spasticity and females visited a broader variety of health care providers than the average user. The participants used fewer providers than they did five years ago. Health care users were not found to be substituting one provider type with another. CONCLUSIONS: Individuals with spinal cord injury in Switzerland use a wide array of medical service providers. All providers were used complementary to each other without redundancies between providers. The use of providers is driven by health-related factors and gender. Old age was not as much a driver for high utilization as described in other settings.

Factors influencing specialized health care utilization by individuals with spinal cord injury: a cross-sectional survey.

STUDY DESIGN: Cross-sectional observational study using data from the second community survey of the Swiss Spinal Cord Injury Cohort Study (Survey 2017) conducted between 03/2017 and 03/2018. OBJECTIVES: To identify facilitators of and barriers to utilizing SCI-specialized outpatient clinic and inpatient care by individuals with spinal cord injury (SCI). SETTING: Community. METHODS: Multivariable logistic regression was used to identify factors influencing (1) the attendance at annual check-ups at SCI-specialized treatment facilities, (2) the utilization of SCI-specialized outpatient clinic care by those who utilized any outpatient clinic care, and (3) the utilization of SCI-specialized inpatient care by those who were hospitalized. Multiple imputation was used to account for missing data. RESULTS: Out of 3959 eligible individuals, 1294 completed the questionnaire (response rate 33%). In the last 12 months, 51% of study participants attended the annual check-up, 33% of outpatient clinic care users utilized SCI-specialized outpatient clinic care, and 44% of those who were hospitalized were hospitalized at a SCI center. Annual check-ups were attended less by women, the elderly, and those with nontraumatic SCI. SCI-specialized outpatient clinic care was less likely to be utilized when individuals with SCI were living with cancer, lived farther away from SCI-specialized treatment facilities or in a minority language region. Specialized inpatient care was less likely to be utilized by women and those with incomplete lesions. CONCLUSIONS: SCI-specialized outpatient clinic care must be provided near the residence of individuals with SCI, otherwise non-specialized care is utilized. The reasons why women utilize SCI-specialized care less frequently than men merits further investigation.

Detecting subgroups in social participation among individuals living with spinal cord injury: a longitudinal analysis of community survey data.

STUDY DESIGN: Longitudinal community survey. OBJECTIVES: To determine subgroups in social participation of individuals living with spinal cord injury (SCI). SETTING: Community. METHODS: Data were collected in 2012 and 2017 as part of the community survey of the Swiss Spinal Cord Injury cohort. Participation was assessed using the 33-item Utrecht Scale of Evaluation of Rehabilitation-Participation evaluating frequency of, restrictions in and satisfaction with productive, leisure, and social activities. Linear mixed-effects model trees were used to distinguish subgroups in participation associated with sociodemographic and lesion characteristics. RESULTS: In all, 3079 observations were used for the analysis, of which 1549 originated from Survey 2012, 1530 from Survey 2017, and 761 from both surveys. Participants were mostly male (2012: 71.5%; 2017: 71.2%), aged on average 50 years (2012: 52.3; 2017: 56.5), with an incomplete paraplegia (2012: 37.5%; 2017: 41.8%) of traumatic origin (2012: 84.7%; 2017: 79.3%). There was limited within-person variation in participation over the 5-year period. Participation varied with age, SCI severity, education, financial strain, number of self-reported health conditions (SHCs), and disability pension level. Among modifiable parameters, the number of SHCs and disability pension level emerged as the most frequent partitioning variables, while education was most informative for participation in productive, leisure, and social activities. CONCLUSIONS: Long-term rehabilitation management and clinical practice should target people most prone to decreased participation in major life domains. Our study indicates that the alleviation of SHCs, engagement in further education, or adjusting disability pension level are promising areas to improve participation of persons living with SCI.

First contact of care for persons with spinal cord injury: a general practitioner or a spinal cord injury specialist?

BACKGROUND: Although general practitioners (GPs) are generally considered as the first point of contact for care, this may be different for persons with complex conditions, such as those with spinal cord injury (SCI). The objective of this study is to understand the differences in long-term care provision by GPs and SCI-specialists, by examining (1) the first contact of care for SCI health problems, (2) the morbidity profile and use of health-care services in relation to first contact, and (3) the factors associated with the choice of first contact. METHODS: In this cross-sectional study based on data derived from the Swiss Spinal Cord Injury Cohort Study Community Survey 2017, the main outcome measure was the reported first contact for SCI-specific care. This information was analysed using the chi-square test and logistic regression analysis of groups based on patient characteristics, use of health-care services and secondary health conditions assessed using the Spinal Cord Injury Secondary Conditions Scale (SCI-SCS). RESULTS: Out of 1294 respondents, 1095 reported their first contact for SCI-specific care; 56% indicated SCI-specialists and 44% specified GPs. On average, participants who first contacted a GP reported higher number of GP consultations (5.1 ± 5.2 vs. 3.9 ± 7.2), planned visits to ambulatory clinics (3.7 ± 7.3 vs. 3.6 ± 6.7) and hospital admissions (GP, 1.9 ± 1.7 vs. 1.5 ± 1.3), but lower number of visits to SCI-specialists (1.7 ± 1.8 vs. 2.6 ± 1.7) and of hospital days (22.8 ± 43.2 vs. 31.0 ± 42.8). The likelihood to contact a GP first was significantly higher in persons ≥75 years old (OR = 4.44, 95% CI = 1.85-10.69), Italian speakers (OR = 5.06, 95% CI = 2.44-10.47), had incomplete lesions (OR = 2.39, 95% CI = 1.71-3.35), experiencing pain (OR = 1.47, 95% CI = 1.04-2.09) or diabetes mellitus (OR = 1.85, 95% CI = 1.05-3.27), but lower for those situated closer to SCI centres (OR = 0.69, 95% CI = 0.51-0.93) or had higher SCI-SCS scores (OR = 0.92, 95% CI = 0.86-0.99). CONCLUSION: Age, language region, travel distance to SCI centres, lesion completeness, and occurrence of secondary conditions play a significant role in determining the choice of first contact of care, however there is still some unwarranted variation that remains unclear and requires further research.
